Hi all, I think I need to fit a twin shower pump to a new shower room I am forming in an on-suite off a bedroom - the shower will be a full body type with three of four heads. The hot water cylinder and cold water tank above it are in a cupboard in another bedroom hence there is poor hot water pressure on the first floor. I think I will only have room for a cold water tank of around 25 litres, will this be big enough to take the cold feed for the shower from - cold pressure to the tank is reasonable - or will the pump drain the tank too quickly? The building is a dormer bungalow with no roof space above the bedroom ceilings. I do not want to fit an electric shower. Any advice appriciated.
